King County Councilman Reagan Dunn announced a plan Thursday to urge state legislators create a “blue alert” system to inform the public about people suspected of injuring or killing law enforcement officers.

The proposal came hours after a man fatally shot a state trooper in Kitsap County. Dunn plans to introduce a motion Monday urging the council to support state legislation to create a “blue alert” system.

“This tragic pattern of injury and death to law enforcement officers in Washington state simply cannot continue,” he said in a statement. “We in government must do everything in our power to protect those who put their lives on the line everyday in order to protect us.”
